Most of the apartment buildings to be remodeled are in the form of wall structures, and walls are very important structural members. When remodeling, there are cases where existing walls are demolished and new walls are installed. If a wall is newly installed, the continuity of the wall from the foundation to the top floor must be ensured. Some slabs prevents the vertical continuity of the reinforced wall. It is because the upper and lower wall reinforcing bars must be connected through the demolished slab and the concrete must be poured. Therefore, in this study, the method to secure the vertical continuity of the reinforced wall during the remodeling will be examined.
This study is to determine the predictability of the ground cavitation by GPR (ground penetrating radar) equipment. Hume pipe, PE pipe, Steel Pipe and EPS (expanded polystyrene) are buried in the test bed. According to detection results, the EPS was not well detected. It received a lot of interference signal of other buried things. Otherwise the buried pipes were well detected.
The purpose of this study is a image processing program development to consider the domestic situation of GPR detection. Therefore the image processing program will be developed to extract and to visualize the measured raw data.
The purpose of this study is an GPR image processing program (GPRiPP) development. And the developed GPRiPP has many image processing functions such as background removal, stacking and Gain function. With the GPR detection results of such as test bed, GPRiPP will be tested and modified in the near future.
Standard reinforcing technology of remodeling will be established through the actual remolding cases. Reinforcement techniques can be classified as a technique of seismic retrofit technologies, vertical and horizontal expansion joint detail, footing reinforcing technology, and general repair method.
In this study, Cavities in Specimens were find using GPR equipment. Results of exploration deadline for plain concrete, reinforced concrete, asphalt, gravel, depending on the type, asphalt pavement was most clearly exploration. Developed GPRiPP can represent a good cavitation through the image processing with the background removal.
This study is to determine the predictability of the ground cavitation by GPR equipment. Water and sewage pipeline buried in sand and soil tanks and to prepare a specimen for exploration of water and air cavities. The sand for a dielectric constant 8, the soil using 6.5 is preferred to extract data for the asphalt pavement condition. After the GPR detections, the cavity in sand tank rather than soil tank is to obtain more precise data.
Because aging sewer on the ground due to cavitation are a lot of social problems occur, the existing aging pipes are to be replaced. But is not easy to accurately detect the aging water and sewage pipes. In this research, we present a technique that can detect defective sewerage pipes used in GPR through Test-bed, which can be used as urban planning resources for water supply and drainage pipes replaced.
This study is to introduce a structural analysis method that can apply a unit modular system to a remodeling extension. The structural analysis process, which can reflect the behaviors between the existing building and the modular system, is performed in a five-staged structural analysis. Therefore, the example of structural analysis of an existing building is introduced.
This study is to establish a structural analysis method that can apply a unit modular system to a remodeling extension. Structural design has to be performed after considering the behaviors between the existing structures and the modular system because the modular system is added after the transformation of existing structures has been processed. The structural analysis process, which can reflect the behaviors between the existing building and the modular system, is introduced in a five-staged structural analysis.
